Objectives: infects the urogenital tract and eyes. Anatomical tropism is correlated with serovars which are characterized according to the variation in the major outer membrane proteins encoded by the gene. The aim of the present study was to determine the distribution of serovars among patients with follicular conjunctivitis in Iran.
Materials And Methods: A total of 68 conjunctival specimens from symptomatic adults were studied for the presence of using polymerase chain reaction (PCR) analysis. Serovars were determined by Omp1 PCR-RFLP analysis.
Results: was detected in 38 (55.9%) of patients with follicular conjunctivitis, with higher prevalence in the younger age groups. Twenty-six (38.2%) of these patients had a history of urinary tract infection. Four distinct serovars were identified in the conjunctiva samples using molecular genotyping. The most prevalent was serovar E, followed by G, I, and F.
Conclusion: Our serovar distribution indicated that chlamydial follicular conjunctivitis usually has a genital source. Genital serovars may cause eye diseases, especially in sexually active adults. On the other hand, conjunctivitis might be the only sign of sexually transmitted infection. Therefore, genotyping in ocular and genital specimens could be beneficial for acquiring more detailed epidemiological information about the etiology of the disease and monitoring treatment success.

Background: Following interventions to eliminate trachoma in the Afar region of Ethiopia, our goal was to reassess the prevalence of trachomatous trichiasis (TT) and trachomatous inflammation-follicular (TF) at the woreda level, and to identify factors associated with the disease.
Methods: Cross-sectional community-based surveys were conducted in 26 trachoma-endemic woredas, employing a standardized approach. Households were selected as the secondary sampling unit.

Purpose: Baseline surveys were conducted in Tigray region, Ethiopia, in 2013. Since then, rounds of azithromycin mass drug administration (MDA) have been delivered in-line with international guidance. The purpose of these surveys was to assess trachomatous inflammation-follicular (TF) prevalence following those treatments to enable the region to plan the next steps towards elimination of trachoma.

Background: Blepharoconjunctivitis poses a diagnostic challenge due to its diverse etiology, including viral infections. Blepharoconjunctivits can be acute or chronic, self-limiting, or needing medical therapy.
Aim: To review possible viral agents crucial for accurate differential diagnosis in cases of blepharoconjunctivitis.

Background: Trachoma programs use the indicator trachomatous inflammation--follicular (TF) to monitor indication for and response to treatment for trachoma at the district level. Alternative indicators, including serologic markers, are increasingly being evaluated for trachoma surveillance. We evaluated seroprevalence of IgG antibodies to the Pgp3 antigen in two districts in Maradi, Niger thought to have low TF prevalence.
